Spin-flavor entanglement in ${\Lambda }_b\to \Lambda D$ and weak phase extraction

Yong Du, Chao-Qiang Geng, Xiao-Gang He +3

We identify a new spin-flavor entanglement structure in ${\Lambda }_b\to \Lambda D$ decays, formed by the correlation between the $\Lambda$ spin and the $D$ flavor states ($D=D^0,{\overline{D}}^0,D_1,D_2$).…
